IMPROVEMENT IN DIES FOR FORMING SPANISH AXES.

Specification forming part of Letters Patent No. 172.252, dated January 18, 1876; application filed April 9, 1875.

CASE D.

To all whom it may concern Be it known that I, LUKE GEATMAN, of Collinsville, in the county of Hartford and State of Connecticut, have invented certain new and useful Dies for Forming Round-Headed Spanish Axes, having eyes of the shape of a wedge with roundedA ends, of 'which the following' is a yspecilication, reference being had to the accompanying drawings, Where- Figure l is what I will term a front view of the dies closed upon the sides of an ax. Fig. 2 is What I will term a side view of the dies closed upon the edges of an ax. Fig. 3 is a view of the linished ax.

These dies can be used in rolls or presses or drops, and for the primary or finishing parts ofthe forging process; but I` prefer to use them forA finish-forging the axes, having the upper die carried on the lower end of a vertically -reciprocating hammer stock, to be operated by suitable mechanism and power,

\ the die being held to its seat by the dovetail tenori al, and the lower die b stationary on the top of an anvil-block, being held to its seat by the dovetail tenon b1. These dies have faces a2 and b2, corresponding in shape and contour to the shapes and contours of the faces or sides of the body of the ax shown in Fig. 3. These Iterm thesurfacing-faces. They also have edging-faces a3 and b3, corresponding in shapes and contours to the shapes and contours of the edge of the ax shown in Fig. 3.

The ax, after being properly heated, is subjected alternately to the action. of the surfacing and edging dies till the desired form is attained, giving axes which are accurately shaped and smoothly linished, and thereby insuring uniformity in the style, design, or4

pattern of the axes produced, andavoiding the multiplicity of small hammer-marks which are found upon axes forged or finished by hand, and which are difcult and expensive to entirely obliterate in the subsequent processes of grinding and polishing, and with the further great advantage of producing better axes much more cheaply than by hand-forging.

These dies are, by preference, of cast-iron. While the Workman is side-surfacing the ax he usually has an eyepin in the eye of the ax. It is obvious that these dies are applicable by changes in size to the manufacture of different-sized axes of thel same design or pattern, and that the bit or blade of the axe can have more or less breadth or angular divergence toward the edge Without altering the dies in substance.

I claim as my invention- Dies a and b, herein described, having faces for side-surfacing and edging axes, of substantially the shape shown and described.

LUKE CHAPMAN.
